I've got a da 50 with just a tank thur it and it runs great. it idels at 2000 rpm and it does'nt pull the plane on the ground and top is 6800 rpm with a 22-8 menzS. both top and bottom are rich. I too was following the other thread and did the taxing around and stuff and never had a problem.

I just hope i dont have the same problems you guys are having.

P.S. guys from i hear this engine will run like crap till it's broken in and switched to syn.
